Changes over 6-months in health-related quality of life in a matched sample of Hispanics and non-Hispanics with heart failure

Racial and Ethnic Differences in Biomarkers, Health Status, and Cardiac Remodeling in Patients With Heart Failure With Reduced Ejection Fraction Treated With Sacubitril/Valsartan

Supplemental Digital Content is available in the text.

Among patients with heart failure and reduced ejection fraction (left ventricular (LV) ejection fraction ≤40%), sacubitril/valsartan (S/V) treatment is associated with improved health status and reverse cardiac remodeling. Data regarding racial and ethnic differences in response to S/V are lacking.

Health Status Disparities by Sex, Race/Ethnicity, and Socioeconomic Status in Outpatients With Heart Failure

OBJECTIVES

This study sought to describe the health status of outpatients with heart failure and reduced ejection fraction (HFrEF) by sex, race/ethnicity, and socioeconomic status (SES).

BACKGROUND

Although a primary goal in treating patients with HFrEF is to optimize health status, whether disparities by sex, race/ethnicity, and SES exist is unknown.

METHODS

In the CHAMP-HF (Change the Management of Patients with Heart Failure) registry, the associations among sex, race, and SES and health status, as measured by the Kansas City Cardiomyopathy Questionnaire-overall summary (KCCQ-os) score (range 0 to 100; higher scores indicate better health status) was compared among 3,494 patients from 140 U.S. clinics. SES was categorized by total household income. Hierarchical multivariate linear regression estimated differences in KCCQ-os score after adjusting for 31 patient characteristics and 10 medications.

RESULTS

Overall mean KCCQ-os scores were 64.2 ± 24.0 but lower for women (29% of sample; 60.3 ± 24.0 vs. 65.9 ± 24.0, respectively; p < 0.001), for blacks (60.5 ± 25.0 vs. 64.9 ± 23.0, respectively; p < 0.001), for Hispanics (59.1 ± 21.0 vs. 64.9 ± 23.0, respectively; p < 0.001), and for those with the lowest income (<$25,000; mean: 57.1 vs. 63.1 to 74.7 for other income categories; p < 0.001). Fully adjusted KCCQ-os scores were 2.2 points lower for women (95% confidence interval [CI]: -3.8 to -0.6; p = 0.007), no different for blacks (p = 0.74), 4.0 points lower for Hispanics (95% CI: -6.6 to -1.3; p = 0.003), and lowest in the poorest patients (4.7 points lower than those with the highest income (95% CI: 0.1 to 9.2; p = 0.045; p for trend = 0.003).

CONCLUSIONS

Among outpatients with HFrEF, women, blacks, Hispanics, and poorer patients had worse health status, which remained significant for women, Hispanics, and poorer patients in fully adjusted analyses. This suggests an opportunity to further optimize treatment to reduce these observed disparities.

Evaluation of Quality of Life in Patients with and without Heart Failure in Primary Care

BACKGROUND

Heart failure (HF) is a major public health issue with implications on health-related quality of life (HRQL).

OBJECTIVE

To compare HRQL, estimated by the Short-Form Health Survey (SF-36), in patients with and without HF in the community.

METHODS

Cross-sectional study including 633 consecutive individuals aged 45 years or older, registered in primary care. The subjects were selected from a random sample representative of the population studied. They were divided into two groups: group I, HF patients (n = 59); and group II, patients without HF (n = 574). The HF group was divided into HF with preserved ejection fraction (HFpEF - n = 35) and HF with reduced ejection fraction (HFrEF - n = 24).

RESULTS

Patients without HF had a mean SF-36 score significantly greater than those with HF (499.8 ± 139.1 vs 445.4 ± 123.8; p = 0.008). Functional capacity - ability and difficulty to perform common activities of everyday life - was significantly worse (p < 0.0001) in patients with HF independently of sex and age. There was no difference between HFpEF and HFrEF.

CONCLUSION

Patients with HF had low quality of life regardless of the syndrome presentation (HFpEF or HFrEF phenotype). Quality of life evaluation in primary care could help identify patients who would benefit from a proactive care program with more emphasis on multidisciplinary and social support.

Improvements in health-related quality of life of patients admitted for heart failure. The HF-QoL study

INTRODUCTION AND OBJECTIVES

Heart failure (HF) is associated with a poor prognosis, both in terms of survival and ongoing symptoms. The objectives of this study were to investigate trends in the health-related quality of life (HRQoL) of a heterogeneous group of HF patients, with a focus on subgroups of particular clinical interest, and to identify determinants of mortality.

METHODS

Prospective study of 883 HF patients discharged from 50 Spanish hospitals and followed for 1 year, during which six HRQoL assessments were carried out using the generic Short Form-36 (SF-36) questionnaire and the specific Minnesota Living with Heart Failure Questionnaire (MLHFQ).

RESULTS

A marked change was noted at the beginning of the study on all dimensions of the SF-36, in its physical (mean 34.1) and mental (mean 40.1) component summary scores, and in the MLHFQ score (mean 37.5). There was a clear improvement in the first month, which subsequently remained unchanged, except in younger patients aged under 40 years whose HRQoL continued to improve progressively. The following predictors of mortality were identified: age, functional class, co-morbidity and baseline HRQoL.

CONCLUSIONS

In patients with HF, HRQoL showed a clear improvement during the first month after hospital discharge but subsequently remained unchanged, except in younger patients, whose HRQoL continued to improve progressively.

A systematic review of community-based health interventions on depression for older adults with heart disease

PURPOSE

This systematic review examined the effectiveness of community-based heart-health interventions on depression outcomes among homebound elderly (64 years and older) with heart disease.

DESIGN AND METHODS

A comprehensive literature search and meta analysis was performed to evaluate randomized controlled trials examining outpatient or home-based interventions. Methodological quality was assessed by standard criteria developed by the Cochrane Collaborative Initiative.

RESULTS

Fifteen studies met our inclusion criteria and all measured depression outcomes. Studies differed in scope and methodological rigor and sample sizes varied widely. Problems in treatment fidelity and masking of group assignment were noted. Great variability was found in depression outcomes due to the differences in methodology and intervention. Five studies reported significant treatment effect on depression; three of those employed home-based interventions and two were outpatient-clinic interventions. Ten studies were included in the meta analysis and the effect sizes (ESs) ranged from -0.39 (in favor of control group) to 0.65 (in favor of treatment group). The mean weighted ES was 0.11 and six studies showed positive ESs.

IMPLICATIONS

Mixed evidence for community-based heart disease interventions on depression outcomes was found. Future research should include sub-analysis of ESs of interventions on depression outcomes by different demographic characteristics of the study sample, common depression outcome measures, and different follow-up periods.

Anxiety and depression in ethnic minorities with chronic heart failure

BACKGROUND

Considerable evidence confirms the high prevalence of anxiety and depression in the patients with heart failure (HF). However, little is known about the relationship of race/ethnicity to psychosocial variables in this population. The purpose of this study was to examine and compare the incidence of anxiety and depression in a cohort of non-Hispanic blacks, Hispanics, and non-Hispanic whites with advanced systolic HF.

METHODS AND RESULTS

Two-hundred forty-one patients (7% non-Hispanic blacks, 22.8% Hispanics, 60.7% non-Hispanic whites) mean age 56.7+/-13.0 years, male (70%), married (81%), retired (75%), New York Heart Association (NYHA) Class III (53.9%), and mean ejection fraction 31.2+/-5.4%) from a single heart transplant facility were asked to complete a series of questionnaires to assess anxiety, depression, perceived control, social support, and financial stability. Non-Hispanic blacks had higher levels of anxiety (P=.048) and depression (P=.026) compared with Hispanics; a similar trend was noted when comparing non-Hispanic blacks and non-Hispanic whites, but these differences were not statistically significant. Perceived control was highest among Hispanics and lowest among non-Hispanic whites (P=.046). In a multivariate model race/ethnicity, perceived control, and social support accounted for 30% of the variance in anxiety while race/ethnicity, NYHA Class, perceived control, and social support accounted for 41% of the variance in depression.

CONCLUSIONS

Our findings reveal that non-Hispanic blacks are more likely to be anxious and depressed than their counterparts. Because patient perceptions of control and social support are related to dysphorias known to influence morbidity and mortality, clinicians should regularly assess patients' concerns and assist in accessing appropriate services and treatments tailored to individual needs. Non-Hispanic blacks warrant increased scrutiny.

Improvement in health-related quality of life after hospitalization predicts event-free survival in patients with advanced heart failure

BACKGROUND

Health-related quality of life (HRQOL) is a major clinical outcome for heart failure (HF) patients. We aimed to determine the frequency, durability, and prognostic significance of improved HRQOL after hospitalization for decompensated HF.

METHODS AND RESULTS

We analyzed HRQOL, measured serially using the Minnesota Living with Heart Failure Questionnaire (MLHFQ), for 425 patients who survived to discharge in a multicenter randomized clinical trial of pulmonary artery catheter versus clinical assessment to guide therapy for patients with advanced HF. All patients enrolled had 1 or more prior HF hospitalizations or chronic high diuretic doses and 1 or more symptom and 1 sign of fluid overload at admission. Improvement, defined as a decrease of more than 5 points in MLHFQ total score, occurred in 68% of patients by 1 month and stabilized. The degree of 1-month improvement differed (P < .0001 group x time interaction) between 6-month survivors and non-survivors. In a Cox regression model, after adjustment for traditional risk factors for HF morbidity and mortality, improvement in HRQOL by 1 month compared to worsening at 1 month or no change predicted time to subsequent event-free survival (P=.013).

CONCLUSIONS

In patients hospitalized with severe HF decompensation, HRQOL is seriously impaired but improves substantially within 1 month for most patients and remains improved for 6 months. Patients for whom HRQOL does not improve by 1 month after hospital admission merit specific attention both to improve HRQOL and to address high risk for poor event-free survival.

Health related quality of life in older Mexican Americans with diabetes: a cross-sectional study

BACKGROUND

The older Hispanic population of the U.S. is growing at a tremendous rate. While ethnic-related risk and complications of diabetes are widely-acknowledged for older Hispanics, less is known about how health related quality of life is affected in this population.

METHODS

Cross-sectional study assessing differences in health related quality of life between older Mexican Americans with and without diabetes. Participants (n = 619) from the Hispanic Established Population for the Epidemiological Study of the Elderly were interviewed in their homes. The primary measure was the Medical Outcomes Study Short Form (SF-36).

RESULTS

The sample was 59.6% female with a mean age of 78.3 (SD = 5.2) years. 31.2% (n = 193) of the participants were identified with diabetes. Individuals with diabetes had significantly (F = 19.35, p < .001) lower scores on the Physical Composite scale (mean = 37.50, SD = 12.69) of the SF-36 compared to persons without diabetes (mean = 43.04, SD = 12.22). There was no significant difference between persons with and without diabetes on the Mental Composite scale of the SF-36.

CONCLUSION

Diabetes was associated with lower health related quality of life in older Mexican Americans. The physical components of health related quality of life uniformly differentiated those with diabetes from those without, whereas mental component scores were equivocal.

Characterization of health-related quality of life in heart failure patients with preserved versus low ejection fraction in CHARM

BACKGROUND

Limited comparative studies assessing the health-related quality of life (HRQL) in heart failure (HF) patients with preserved vs. low ejection fraction (LVEF) have been disparate.

AIMS

The aims of this study were a) to characterize HRQL in a large population of HF patients with preserved and low LVEF and b) to determine the factors associated with worse HRQL.

METHODS

Patients with symptomatic HF (NYHA Class II-IV) enrolled in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) HRQL study completed the Minnesota Living with Heart Failure questionnaire at randomization. Patients were stratified into 2 HF cohorts: preserved LVEF (>40%) and low LVEF (<or=40%).

RESULTS

In 2709 of the eligible 2744 (98.6%) patients, the summary scores ranged from 0 to 105 (mean 40.9). There were no differences in overall responses of HF patients with preserved vs. low LVEF (41.1 vs. 40.8). Independent factors associated with worse HRQL in both populations included female gender, younger age, higher body mass index, lower systolic blood pressure, greater symptom burden, and worse functional status.

CONCLUSIONS

In symptomatic HF patients, HRQL is equally impaired in both preserved and low LVEF populations. Targeting improvement in symptoms and HRQL is an important treatment objective in all HF patients.

Psychosocial and Cultural Influences on Cardiovascular Health and Quality of Life Among Hispanic Cardiac Patients in South Florida

This study examined whether psychosocial and cultural factors were related to four dimensions of cardiac-related quality of life (global, physical, emotional, and social functioning) in 120 Hispanic coronary heart disease (CHD) outpatients in south Florida. Survey data were collected on sociodemographic (age, gender, socioeconomic status), psychosocial (depression, social support), and cultural factors (acculturation, familism, fatalism), and quality of life. Medical data on CHD severity (New York Heart Association class, time since diagnosis) were obtained from patients' clinic records. Hierarchical regression analyses revealed that women and patients with more severe CHD had poorer quality of life than men or patients with less severe CHD. Psychosocial and cultural factors were associated with poorer quality of life after controlling for sociodemographic and medical variables: Depression was associated with all four quality of life dimensions (p < .001); and fatalism (p < .05) was associated with lower social functioning in women. These findings identify Hispanic subgroups with poor cardiac-related quality of life that can benefit from special outreach.

Randomized Controlled Trial of Telephone Case Management in Hispanics of Mexican Origin With Heart Failure

BACKGROUND

Disease management is effective in the general population, but it has not been tested prospectively in a sample of solely Hispanics with heart failure (HF). We tested the effectiveness of telephone case management in decreasing hospitalizations and improving health-related quality of life (HRQL) and depression in Hispanics of Mexican origin with HF.

METHODS AND RESULTS

Hospitalized Hispanics with chronic HF (n = 134) were enrolled and randomized to intervention (n = 69) or usual care (n = 65). The sample was elderly (72 +/- 11 years), New York Heart Association class III/IV (81.3%), and poorly educated (78.4% less than high school education). Most (55%) were unacculturated into US society. Bilingual/bicultural Mexican-American registered nurses provided 6 months of standardized telephone case management. Data on hospitalizations were collected from automated systems at 1, 3, and 6 months after the index hospital discharge. Health-related quality of life and depression were measured by self-report at enrollment, 3, and 6 months. Intention to treat analysis was used. No significant group differences were found in HF hospitalizations, the primary outcome variable (usual care: 0.49 +/- 0.81 [CI 0.25-0.73]; intervention: 0.55 +/- 1.1 [CI 0.32-0.78] at 6 months). No significant group differences were found in HF readmission rate, HF days in the hospital, HF cost of care, all-cause hospitalizations or cost, mortality, HRQL, or depression.

CONCLUSION

These results have important implications because of the current widespread enthusiasm for disease management. Although disease management is effective in the mainstream HF patient population, in Hispanics this ill, elderly, and poorly educated, a different approach may be needed.

Testing the psychometric properties of the Minnesota Living with Heart Failure questionnaire

BACKGROUND

Health-related quality of life (HRQOL) is an important outcome in patients with heart failure. One of the most commonly used instruments to measure HRQOL in this population is the Minnesota Living With Heart Failure Questionnaire (LHFQ). Although the psychometric properties of the LHFQ have been tested, the results do not definitively support the psychometric soundness of the instrument.

OBJECTIVE

To examine the psychometric properties of the LHFQ.

METHOD

Data from 638 patients with heart failure were used to assess the reliability, homogeneity, representativeness, discriminative ability, and construct validity of the LHFQ before and after deletion of 5 items that showed lack of representativeness and contributed to inadequate factor structure.

RESULTS

Cronbach's alphas for the LHFQ Total and subscales were greater than .80. Interitem correlation coefficients in 17 of the 21 items, item-total correlation coefficients in 20 items, and discriminative ability in all items were acceptable. The total and both subscales of the LHFQ differentiated New York Heart Association functional groups. The Physical subscale was moderately related to the physical measures (the Specific Activity Scale and symptom status), whereas the emotional subscale was weakly related to the measures. The results of item p level testing and factor analysis demonstrated that 7 items were consistently problematic and 5 items were recommended to be deleted. The results of the reliability, homogeneity, and construct validity after deletion of these items demonstrated that the psychometric properties of the LHFQ were improved as a result.

DISCUSSION

The initial results provided additional support for the reliability and substantial evidence for the validity of the LHFQ. However, the results of item and factor analyses did not fully support the psychometric soundness of several items. The psychometric properties of the LHFQ after deleting these items were improved. These results could provide researchers and clinicians a more useful measure of HRQOL.

Life satisfaction and disability after severe traumatic brain injury

OBJECTIVE

To assess the relationships between life satisfaction and disability after a severe traumatic brain injury (TBI).

DESIGN

Cross-sectional study, including 75 patients 2 years or more after a severe TBI.

METHODS

Life satisfaction was assessed with the Subjective Quality of Life Profile. Impairments, activities and participation were assessed with standardized tests.

RESULTS

The satisfaction profile was flat, i.e. the majority of items obtained mean satisfaction scores close to 0, suggesting that participants felt indifferent to these items or in other words that they were neither satisfied nor unsatisfied. Patients were on average slightly dissatisfied with their cognitive functions, physical abilities and self-esteem. A factor analysis revealed three underlying factors. The main finding was that the relationships between life satisfaction and disability were not linear: the lowest satisfaction scores were reported by participants with moderate disability rated by the Glasgow Outcome Scale, while individuals with severe disability did not significantly differ from the good recovery group.

CONCLUSION

Life satisfaction is not linearly related to disability after severe TBI.

Gender, Ethnicity, and Cardiovascular Disease

Although the influence of gender and ethnicity on cardiovascular disease has been understudied, cardiovascular nurse researchers have contributed significantly to the existing body of knowledge. This article distinguishes between the constructs of "gender versus sex'' and "ethnicity versus race,'' acknowledging that the terms are often used interchangeably in research. A sampling of the substantial contributions of cardiovascular nurse researchers related to gender and ethnicity in the areas of symptoms of cardiovascular disease; risk factors and prevention; delay in seeking care, diagnosis, and treatment; recovery and outcomes; and cardiac rehabilitation is highlighted. Recommendations for future research include publishing research data by gender and ethnicity subgroups even though statistical comparisons may not be feasible, and increasing cardiovascular disease research in minority populations such as Asian Americans, Pacific Islanders, Native Americans, and Hispanics. Finally, we challenge cardiovascular nurse researchers to shift from the documentation of disparities toward designing and testing of interventions to eliminate health disparities.
